Methods Of Using Certificate-Based Security With Drone Identity And Broadcasting

5. The method of claim 1, wherein the signed beacon type message further includes the certificate or the certificate is included in a different signed beacon type message.

8. The method of claim 7, wherein the signed beacon type message is a Bluetooth 5 extended advertising frame or a Wi-Fi Neighbor Awareness Networking (NAN) service discovery frame.

10. The method of claim 9, wherein the signed beacon type message is an ASTM F3411-19 authentication message or an IEEE 1609.2 signed message contained within an ASTM F3411-19 compliant frame.

11. The method of claim 9, wherein a hit portion of the certificate hash corresponds to a universally unique identifier (UUID) or session identifier (session ID) assigned to the UAS, its operator or a tuple of the UAS and its operator.

12. The method of claim 11, wherein the hit portion is a first or last 64, 92, 120 or 128 bits of the certificate hash.

14. The method of claim 1, wherein the certificate is an implicit format certificate not including a full version of the public key.

15. The method of claim 1, wherein the certificate includes a public key reconstruction value, the public key reconstruction value configured to allow the public key to be reconstructed.

16. The method of claim 1, wherein the message payload is an Automatic Dependent Surveillance—Broadcast (ADS-B) message to be broadcast over a small beacon or service advertisement frame.

17. The method of claim 1, wherein sending the signed beacon type message in one or more broadcast transmissions from the device comprises sending the signed beacon type message in a plurality of broadcast pages or broadcast frames from the device.

19. The method of claim 18, wherein the certificate was received from the device in another beacon type message.

20. The method of claim 18, wherein processing the signed beacon type message in response to determining that the signed beacon type message is valid comprises determining an unmanned aerial vehicle identity or operator of an unmanned aerial vehicle identity at least in part using the signed beacon type message.

21. The method of claim 20, wherein a broadcast identifier is contained within a signing certificate and the broadcast identifier is a cryptographic output of a keyed hash, message authentication code algorithm or public key signing algorithm.

22. The method of claim 21, wherein the keyed hash, message authentication code or public key signing algorithm is invoked repeatedly with a unique counter input or nonce, and each output constitutes another identifier of a short-lived broadcast ID certificate associating an unmanned aerial vehicle and unmanned aerial vehicle operator.

27. The device of claim 23, wherein the signed beacon type message further includes the certificate or the certificate is included in a different signed beacon type message.

30. The device of claim 29, wherein the signed beacon type message is a Bluetooth 5 extended advertising frame or a Wi-Fi Neighbor Awareness Networking (NAN) service discovery frame.

32. The device of claim 31, wherein the signed beacon type message is an ASTM F3411-19 authentication message or an IEEE 1609.2 signed message contained within an ASTM F3411-19 compliant frame.

33. The device of claim 31, wherein a bit portion of the certificate hash corresponds to a universally unique identifier (UUID) or session identifier (session ID) assigned to the UAS, its operator or a tuple of the UAS and its operator.

34. The device of claim 33, wherein the bit portion is a first or last 64, 92, 120 or 128 bits of the certificate hash.

36. The device of claim 23, wherein the certificate is an implicit format certificate not including a full version of the public key.

37. The device of claim 23, wherein the certificate includes a public key reconstruction value, the public key reconstruction value configured to allow the public key to be reconstructed.

38. The device of claim 23, wherein the message payload is an Automatic Dependent Surveillance—Broadcast (ADS-B) message to be broadcast over a small beacon or service advertisement frame.

39. The device of claim 23, wherein the processor is configured with processor-executable instructions to send the signed beacon type message in one or more broadcast transmissions from the device by sending the signed beacon type message in a plurality of broadcast pages or broadcast frames from the device.

41. The broadcast receiver device of claim 40, wherein the certificate was received from the device in another beacon type message.

42. The broadcast receiver device of claim 40, wherein the processor is further configured with processor-executable instructions to process the signed beacon type message in response to determining that the signed beacon type message is valid by determining an unmanned aerial vehicle identity or operator of an unmanned aerial vehicle identity at least in part using the signed beacon type message.

43. The broadcast receiver device of claim 42, wherein a broadcast identifier is contained within a signing certificate and the broadcast identifier is a cryptographic output of a keyed hash, message authentication code algorithm or public key signing algorithm.

44. The broadcast receiver device of claim 43, wherein the keyed hash, message authentication code or public key signing algorithm is invoked repeatedly with a unique counter input or nonce, and each output constitutes another identifier of a short-lived broadcast ID certificate associating an unmanned aerial vehicle and unmanned aerial vehicle operator.
